When you add extra oil to the fuel you are effectively leaning the carb jetting. This can make the engine run hotter and seize. -

no i mean 2tOriginally posted by widowmaker:u mean adding addictives to ur fuel? i noe the lower octane,,, the more fuel power there is -
i think this onli applies to extreme quantities..Originally posted by nismoS132:no i mean 2t -
Think so too. Cause too little 2T will also cause more friction between then piston and block and therefore more heat right.Originally posted by ah_tee:i think this onli applies to extreme quantities.. -
actually i m abit confused
dosen't
too much 2T=running rich ? -
no that's too much petrol
-
find the sparkplug one better to see whether too lean or too rich
piston rarely got chance see or lu lu also -
geee, must have it up somewhere when i first startedOriginally posted by nismoS132:no that's too much petrol
so petrol have cooling qualities? -

overshot then overheat liao? -
yup!Originally posted by ah_tee:so petrol have cooling qualities? -
that's why i always say, premix is not suitable for street use. if you're gonna premix, you'll need a big big tub, a measuring cylinder, a calculator (or a really good head), a big spoon, some garlic, pepper, sliced onions... erm.. oopsOriginally posted by ah_tee:isnt this risky for premix users?

anyway if u premix, it's best to finish your entire tank in 1 shot, like they do at the races, becoz when you refuel, you get the mixture all mixed up (pun, sue me), that and certain brands of 2t are prone to settling after some time of idle (ie. a747) -

true true, actually premix risky biz
over mix foul plug, cannot start
under mix seizure, no gd no gd -
why the NSR engine is so so so much more superior
There are three types of plated cylinders, Kawasaki Electrofusion, hard-chrome, and nickel silicon carbide. There are several variations of the nickel silicon carbide process but the most common trade name is Nikasil. The nickel-based processes have many advantages over hard-chrome, Electrofusion, and sleeving. Nickel attracts oil and is an excellent carrier material for silicon carbide particles, a wear resistant material that carries the load of the piston. This material is electro-plated right on to the aluminum cylinder for the optimum thermal efficiency. Nickel can be honed with diamond stones which leave distinctive peaks and valley scratches in the cylinder wall which retain oil and provide a certain bearing ratio between the running surfaces of the bore.
